CARD-WASTE TRANSMITTER.

SPECIFICATION forming part of Letters Patent No. 508,487, dated November 14, 1893.

7 Application filed Tune 16, 1892- Serial No. 4-.36,986-' (No model.)

- To wZZ whom it may concern.-

Be it known that we, ROBERT B. ROBINSON and-EDWARD P. CoNLEY, citizens of the Dominion of Canada, residing at Sherbrooke, in the" county of Sherbrooke and Province of Quebec, Canada, have invented certain new and 'useful Improvements 'in Gard- Waste Transmitters; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, and

' to figures of reference marked thereon, which form apart of this specification.

This invention relates to an attachment for cardingmachines, particularly that class in which card-waste, or waste side ends are produced.

The object of our invention is to enable such waste to be re-entered, preferably in the second breaker card, in an even and continuous manner, and in this way such material, heretofore used in various other ways quite frequently at a loss is taken from the condensing rolls and caused tointermingle again I inthe same lot from which it originated. One

of the principal advantages is the ability to work up each lotcompletely no matter how; small the quantity of stock.

Briefly stated, our invention is embodied in a transmitter, which consists in a system of tubes for air'draft connecting with a common fan, combined with a set of feed rolls,;which are adapted to feed positively the waste sideends into a tube designed forits transmission, and further our invention consistsin so mounting and arranging saidfeed rolls as to prevent escape of the air blast; further, in the arrangements of the several operative parts, which shall cause the waste ends to be returned in a continuous manner to the machine in the same condition, as when said material emerges from the condensing rolls.

The drawings accompanying this specification represent in Figure 1. a side elevation of carding machinery with the transmitter embodying our invention in position. Fig. 2 is a vertical section longitudinally of the air tube. Fig. 3 is an end view. Fig. 4 isa diagrammatic View showing a single fan with the air tube system applied to several finisher cards.

In the drawings in Fig. l. is shown a side elevation of carding machinery of any improved design and construction to which our invention may be applied. This machinery is merely for purposes of illustration,and is composed of a second breaker card at 2, a finisher card at 3, and two groups of condensing rolls 4:, 4, an upper and a lower set, together with a spool stand 5 upon which are mounted spools 6, 6, while spool drums are indicated at 7 7, and their pulleys at 8 8 As before premised this carding machinery is supplied with some kind of a feed under that class which creates waste side-ends. One of such ends is indicated in- Fig. 1 at 9. The object of our invention is to return such material and again unite it with the stock in process, it being observed that our card waste transmitter is particularly applicable to the treatment of wool. This waste may be re-entered either at the second breaker card, or at the feed-box (not shown) or elsewhere as it may be deemed desirable.

To carry out our invention and to positively guide and direct the card waste usually in the form of a-loose strand or roving, we take such material on each side of the machine and lead it down immediately after .it emerges from the condensing rolls and enter it between feed rolls 10, 12. Said rolls are suitably mounted in a box or casing 13 secured .upon an' air tube 14, the major portion of which is positioned beneath the floor of theroom, see Fig. 1. The lower end of this casing is open, while the upper end. is closed by'means of hinged covers 15 fitted with a short guide tube 16 through which the card waste enters.

To prevent the escape of air, which would oppose the entrance of the card waste within the tube, we have disposed two spring plates 17 which bear against the rolls and serve as closing devices therefor. By such an arrangeair tube at 19, and branch pipes at 14, to every machine, one on either side to take the card waste ends.

The pulleys for actuating the spool drums are shown at 8, as before alluded to. In order to cause the card waste to travel at the same rate of speed as that portion of the stock in process of being spooled, toothed wheels or gears 20, see Fig. 3, are mounted on the shafts of the feed rolls, and a pulley 21 with difierential faces is connected by a band 23 to the spool drum pulley 8. By this method the slack of the band is compensated for and the card waste in a continuous strand, except where an occasional break occurs is guided directly by positive means from the condensing rolls and caused to enter a tube through which an air current is constantly passing, whence it is returned to be again entered With the material in process. This tube is connected at one end with the fan, while its delivery end is located at any point where the waste ends are to re-enter the machine. The waste made by the ends is thus easily and readily disposed of, while among the advantages is the saving of labor to card-tender, combined with the fact that every portion of a small lot of material can be worked up; moreover the apparatus is applicable to every card of whatever make.

We do not desire to claim an air-current for the transmission of the waste ends, since such method is well known in the arts for the conveyance of material of every description, but we consider our invention is embodied in conducting by positive means card waste within a tube through which air is passing; further in preventing the escape of air at the point of entrance of the waste ends, and moreover in transmitting said waste to some return point on the machine and in the same condition as when it emerged from the condensing rolls.

What we claim is- 1. The combination with a carding engine having a group of condensing rolls, and a tube for air blast, of feeding devices located in proximity to said rolls and operating to receive the waste ends from said rolls and to positively introduce the said waste ends within said tube, and means for preventing the escape of air at the point of entrance of such waste ends within the tube, substantially as explained.

2. In combination with a finishing card its condensing rolls, and a tube adapted to re ceive a suitable forced draft, a casing attached to and communicating with said tube, feeding rolls to advance the card waste within the tube, and spring plates bearing upon the feeding rolls-to prevent the escape of air adjacent to said rolls, substantially as stated and specified.

3. In combination with a group of condensing rolls, and a tube adapted to receive a forced air draft, a card waste transmitter composed of a receptacle mounted upon said tube and open at the bottom with a movable top adapted to admit the card waste therethrough, and feed rolls to advance said card waste, together with plates bearing upon the feeding rolls to prevent escape of air adjacent to said rolls, all operating substantially asdescribed.

4. In combination with a carding engine having two or more series of condensing rolls, and a single fan, a tube system for forced draft, one end of said system being united with the fan, and positive feeding devices for receiving the waste ends from said rolls and for causing the waste ends to enter the tube system, and sealing or closing devices adapted to prevent escape of air, where the waste ends enter said tube system, substantially as stated and set forth.

5. The combination with a group of condensing rolls, a fan, and an air tube from said fan,0f aoasing mounted upon said tube, feed rolls within said casing, the spring plates adjacent to said rolls, toothed gears for connecting said feed rolls, and mechanism adapted to feed the waste end within the tube at a rate corresponding to the speed of thewinding spools, substantially as described.

In testimony whereof we aflix our signatures in presence of two witnesses.
